Our PRO masks are tested to filter 99.6% of viruses and bacteria.
Viruses usually travel on droplets of water, which are very large. The mask will block these particles.
Our PRO mask filters are treated with silver, which works to enhance the anti-viral properties of the technology.
We have also written a blog on our website related to protecting yourselves against Covid-19, which you may read from the link below:
